It should end up very well. Fewer females, with a desire for a low birthrate should be the saving of China, by reducing their 1 1/2 billion population down to a survivable size in a century or two. Less fighting for resources with us and others, good result.
While I hope you are correct;what you say looks good on paper, but I fear that you have now millions of young men who want wives and have none available in their immediate surroundings. I don’t think we will see these young men seeking after celibacy and a retiring lifestyle. China is militarizing as fast as it can. Her leaders are very happy to have such human resources available for cannon fodder. Chinese leadership may hold out the carrot of “To the victor goes the spoils”...and for many of those Chinese young men, some of those spoils could be another country’s women.
